Hello,
I'm running postscreen and I'm wondering about a setting. For
postscreen_dnsbl_action, and postscreen_greet_action I've got them set
to enforce. My problem is while it works I get clients that are repeat
customers after they've already been dealt with. Should I change these
to drop?
# For postscreen
postscreen_access_list = permit_mynetworks,
cidr:/etc/postfix/postscreen_access.cidr
postscreen_dnsbl_threshold = 2
postscreen_dnsbl_sites = zen.spamhaus.org*2
bl.spamcop.net*2
b.barracudacentral.org*3
postscreen_dnsbl_action = enforce
postscreen_greet_action = enforce
postscreen_cache_map = proxy:btree:${data_directory}/postscreen_cache
postscreen_cache_cleanup_interval = 0
Thanks.
Dave.
